I'm a little confused on what you mean..
I may have applied brake pressure after the "lack of power" feeling but I'm unsure. This may have really locked up the brakes and after the tires locked up I for sure applied the brakes and controlled the car to a stop. I don't have power brakes, or power steering so it was a rather terrifying experience.
I've never replaced any brake hoses. I'm a new owner to this duster, I bought it about 6 months ago. Had a cam go flat and I rebuilt the carb, added msd ignition and wires, interior work, etc etc. I've put maybe 1000 miles on it..if that.
Other people have agreed that it may be a brake problem so I wan't to cover everything and find the problem before I take it on a drive.
Will update and add pictures as I tear into it.
